CVE-2020-8660

5.3 mediumEPSS 0.6%

Medium (5.3) in envoyproxy envoy. EPSS 0.6% chance of exploitation in the next 30 days.

CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.
